SPINDLE OF TEXTILE-MACHINES.

Specification of Letters Patent.

Patented April 30, 1907.

Application filed March 26.1906. Serial h'c 308,077.

To all whom, it may concern.-

Be it known that I, HENRY Cause, a subject of Great Britain, residing atBlaekley, Manchester, in the county of Lam aster, England, engineer,have invented new and useful Improvements in and Relating to the Spindles of Textiledtiachines, of which the following is a specification.

My invention relates to the spindles of textile machines and has for itsobjects to minimize friction in the spindle hearings, to reduce theamount of driving power required and to increase the steadiness inrunning.

In carrying my improvements into effect I form the spindle of anysuitable size and shape and I mount it in a sleeve or holster supportedon ball bearings between two arms or carrier brackets secured to abolster rail or equivalent part. These arms terminate in rings whichhave annular grooves on the faces adjoining the sleeve and thecorresponding faces of the sleeve have similar grooves forming ballraces in which are placed two series of balls upon which the sleeve isfree to be rotated.

The ring on the upper arm is open and the ring on the lower arm isclosed and in it is formed a footstep to receive the foot of the spindlewhich is passed down through the upper ring and through the sleeve intothe footstep. The spindle is connected to the sleeve not positively butindirectly by means of a balloon shaped or other suitably shaped springor springs compressed and confined between the spindle and the interiorof the sleeve or in place of the spring or springs I may employ anyother suitable elastic cushion to insure the rotation of the spindlewith the sleeve. The sleeve may be driven in any convenient manner butpreferably and according to my invention it is driven frictionally by adisk secured upon a hollow or other shaft placed below the bolsterbearing and in contact with a collar of leather or other suitablematerial fiXed upon the sleeve, say at about mid-length, The frictiondisk is by preference formed of metal the edge of which is in-turned soas to overhang the body of the disk and is slit at intervals to give itelasticity and on this in-turned edge I mount a ring of leather or othersuitable material to form a friction surface which makes contact withthe friction collar on the sleeve; consequently when the shaft is drivenwhich it may be in any convenient way, each friction disk secured uponit drives a sleeve or more than t i l i one sleeve and so gives motionto a spindle, or spindles. I provide the necessary openings or groovesto form oil passages for the lutrication of the ball bearings andspindle footstep.

In the actompanying two sheets of drawings-Figure is a sectionalelevation of my improved spindle. Fig. 2 is an elevation taken at rightangles to Fig. 1. Figs. 3 and t are similar views to Fig. 2 but showalterna tive modes of mounting the friction driving ring. Fig. 5 is anelevation of my improved spindle as arranged for band driving instead offriction driving.

Referring first to Figs. 1 and 2,(L designates the spindle; b the sleeveor bolster; c the top open ring; (I the bottom closed ring or footstep cthe balls carried in races formed by grooves in the contiguous surfacesof the sleeve or bolster and the top and bottom rings; fthc arms forminga carrier bracket secured by the shank f or in any other convenient wayto a bolster rail or other part, not shown; 9 the balloon shaped springscompressed between the spindle and the interior of the sleeve orbolster; h an ordinary gravity holding down catch or device forpreventing the withdrawal of thcspindle while (letting the shaft drivenin any convenicnt manner; /c the friction disk secured thereon; m aspring metal ring riveted to the disk; n the leather or other suitablering forming a friction surface and 0 screws passing through the diskand bearing on the metal ring m in order to press its friction ring ainto contact with the friction collar 7) on the sleeve. The ring (Iforming the spindle footstep is screwed into or otherwise secured in thelower carrier armfwhile the upper ring 0 is held in a clip formed in theupper carrier arm and closed by a screw q. Any convenient method ofconnecting the balloon shaped springs g to the spindle may be employedas for example a pin .9 in the spindle may project into a slot orholc inthe spring and proj ections g on the spring may engage grooves in theinterior of the sleeve or bolster, as shown, if required but in practicesuch projections and grooves may not be necessary. Again, instead of theballoon shaped or other shaped springs I may employ any other suitableform of elastic cushion to form the connection between the spindle andthe sleeve or bolster.

In Fig. 3 the spring metal m carrying the friction surface a is shownattached to the outer edge of the disk 70 and bent over and back to theinner side but in all other respects the arrangement is the same as thatalready described.

In Fig. 4 the friction disk 75 is shown mounted horizontally upon avertical shaft or spindle this arrangement enabling the i V ters Patentof the United States isfrietion surface a to drive more than one spindlesimultaneously.

In Fig. 5 the spindle a is mounted in its sleeve or bolster 6 supportedon ball bear ings as already described; but in this case instead offriction driving a wharf t is shown formed on the sleeve or bolster toenable it to be driven by a band.

I wish it to be clearly understood that the drawings merely illustrateexamples of some out of many arrangements and constructions which couldbe adopted without departing i from the characteristic features of myinvention which consists essentially 1n mounting the spindle in a sleeveor bolstersupported preferably on ball bearings and driven preferably byfriction the spindle being connected but not positively, to the interiorof the sleeve or bolster by a suitable form of spring or elastic cushionconnection.

W hat I claim and desire to secure by Letname to this specification inthe presence of two subscribing witnesses.
